Works and looks great

I used these rocks to build a tower for my devil's hand coral. Easily arranged and epoxied together. Nice coloring. Would work great for fragging.

It leave a pink residue on hands when cleaning the rocks , I think it shouldn’t that’s why 4 starts , they are beautiful rocks. Below a picture of 2 bags 2.5lb on a 38 gal fish tank (30x22.5 inch), waiting for a second delivery of bigger rocks.

Good quality my fish and coral seem to really enjoy the rocks

Everyone else is right. Its just a bunch of rubble pieces. No rock to speak of. But I'm gluing it together to make a rock structure. Could use less of the fake purple color. Comes off on everything. Your hands, your work surface, in the water... rinse the rock first.

Box with assorted sizes. Caribsea always delivers on its promises.

Comes with a ton of pieces. Looks great just rinse them off first. I will but again to build cool structures

There are plenty of rocks in the box. All are similarly sized. They are perfect if you’re fragging. I clipped frag plugs off of my degas that just arrived, and glued the discs onto these rocks. I was able to create a few islands, and glued a few of these little rocks onto larger pieces of live rock.
